Development of a Self-etch Adhesive for Resin-modified Glass Ionomers
Journal of Dental Research, 2006The favorable self-adhesiveness of resin-modified glass ionomers (RMGIs) might be even further improved if the time-consuming and technically sensitive etch-and-rinse pre-treatment step with polyalkenoic acids could be avoided. We undertook this study to assess the effectiveness of an experimental self-etch adhesive for RMGIs that does not need to be ...

Hydrolytic degradation and cracks in resin‐modified glass‐ionomer cements
Journal of Biomedical Materials Research Part B: Applied Biomaterials, 2004AbstractWater‐absorption affects the basic properties of resin‐modified glass‐ionomer cements (RMGICs). Fick's law is usually invoked to explain the absorption process. The purpose of this study is to show that the absorption in accordance with the Fickian model cannot be extended to the whole of the specimen, and that microcrack formation is the main ...

Surface finishing of resin-modified glass ionomer.
General dentistry, 2004This study utilized spectrophotometry to evaluate in vitro superficial dye deposition on resin-modified glass ionomer, following different surface finishing and polishing treatments. Materials that were photocured adjacent to the mylar strip produced the surfaces with the lowest mean after superficial staining.

Resin-modified glass-ionomer cements.
The International journal of prosthodontics, 1991The recently developed dual-setting resin glass-ionomer cements are discussed, and the question of whether they are the true glass-ionomer cements is addressed. Their chemistry and properties are examined and compared with conventional glass-ionomer cements.

Failure of resin-modified glass-ionomers subjected to shear loading
Journal of Dentistry, 1999The mechanism of bond failure of resin-modified glass-ionomers is unknown. This study examined the failure on shear loading at the dentine interface of these materials. Twenty-five teeth (embedded in acrylic blocks) were sectioned longitudinally to expose a flat dentine surface.

Solubility of a resin-modified glass ionomer cement.
ASDC journal of dentistry for children, 1998Thirty standardized discs were fabricated from a resin-modified glass ionomer cement (Vitremer -3M) using three different powder/liquid ratios. All specimens were immediately weighed. Specimens were stored in artificial saliva for thirty days. Twice each day the specimens received a 30-min.

Fracture toughness of resin-modified glass ionomers.
American journal of dentistry, 1996To measure and compare the fracture toughness of a multi-purpose resin composite, four light-cured glass ionomers, one light-cured resin ionomer, and two silver-containing glass ionomers.Ten specimens were fabricated for each of the eight materials: Herculite XRV, Fuji II LC, Photac-Fil, Vitrebond, Photac-Bond, VariGlass VLC, Ketac-Silver, and Miracle ...

Clinical evaluation of a resin-modified glass-ionomer adhesive system.
Operative dentistry, 1998One hundred cervical caries-free, nonundercut lesions were restored in 13 patients of mean age 60.5 years, using Silux Plus or Estio LC resin composite bonded with Fuji Bond LC. Patients were recalled at 6 months and 1 year. A 1-year cumulative retention rate of 98% was recorded, while marginal staining was absent. ©Operative Dentistry, 1998.

Resin-modified glass ionomer cements: Fluoride release and uptake
Acta Odontologica Scandinavica, 1995The aim was to study the short- and long-term fluoride release from resin-modified glass ionomer cements (GIC). The aim was also to determine the effect of fluoride treatment of 9-month-old specimens, consistency of the mix, and pH of the environment on the fluoride release. GIC test specimens were continually exposed to running water, and the fluoride
